| intermediate bronchus | The portion of the right main bronchus between the upper lobe bronchus and the origin of the middle and inferior lobe bronchi. Synonym: bronchus intermedius. (05 Mar 2000) |

| intermediate carcinoma | <tumour> Obsolete term for basosquamous carcinoma (05 Mar 2000) |
| intermediate care facilities | Institutions which provide health-related care and services to individuals who do not require the degree of care which hospitals or skilled nursing facilities provide, but because of their physical or mental condition require care and services above the level of room and board. (12 Dec 1998) |
| intermediate cephalic vein | <anatomy, vein> The lateral branch of the median antebrachial vein that joins the cephalic vein near the elbow. Synonym: vena intermedia cephalica, median cephalic vein, vena mediana cephalica. (05 Mar 2000) |
| intermediate cervical septum | A thin septum composed of glia fibre and leptomeningeal connective tissue in the cervical spinal cord marking the border between the gracile fasciculi and cuneatus of the dorsal funiculus. Synonym: septum cervicale intermedium. (05 Mar 2000) |
| intermediate cubital vein | <anatomy, vein> A vein which passes across the anterior aspect of the elbow from the cephalic vein to the basilic vein; commonly this vein is replaced by intermediate basilic and intermediate cephalic veins. The median cubital vein is often used for venipuncture. Synonym: vena intermedia cubiti, intermediate cubital vein, vena mediana cubiti. (05 Mar 2000) |
| intermediate cuneiform bone | A bone of the distal row of the tarsus; it articulates with the medial and lateral cuneiform, navicular, and second metatarsal bones. Synonym: os cuneiforme intermedium, mesocuneiform, middle cuneiform bone, second cuneiform bone, wedge bone. (05 Mar 2000) |
| intermediate density lipoprotein | Class of lipoproteins formed in degradation of very-low-density lipoproteins; about half are cleared quickly from the plasma into the liver by receptor-mediated endocytosis; the other half are degraded into low density lipoproteins. (05 Mar 2000) |
| intermediate disk | <cell biology> The line formed where actin filaments attach between two sarcomeres. (11 May 1997) |
| intermediate dorsal cutaneous nerve | <anatomy, nerve> The lateral terminal branch of the superficial peroneal nerve, supplying the dorsum of the foot and dorsal nerves to the toes (except for adjacent parts of great and second toes). Synonym: nervus cutaneus dorsalis intermedius. (05 Mar 2000) |
| intermediate filament | <cell biology> A class of cytoplasmic filaments of animal cells so named originally because their diameter (nominally 10 nm) in muscle cells was intermediate between thick and thin filaments. Unlike microfilaments and microtubules, the protein sub units of intermediate filaments show considerable diversity and tissue specificity. See: cytokeratins, desmin, glial fibrillary acidic protein, neurofilament proteins, nestin and vimentin (18 Nov 1997) |
| intermediate filament proteins | Filaments 7-11 nm in diameter found in the cytoplasm of all cells. Many specific proteins belong to this group, e.g., desmin, vimentin, prekeratin, decamin, skeletin, neurofilin, neurofilament protein, and glial fibrillary acid protein. (12 Dec 1998) |
| intermediate filaments | Cytoplasmic filaments intermediate in diameter (about 10 nanometers) between the microfilaments and the microtubules. They may be composed of any of a number of different proteins and form a ring around the cell nucleus. (12 Dec 1998) |
| intermediate ganglia | Small sympathetic ganglia most commonly found on the communicating branches in the cervical and lumbar region. Synonym: ganglia intermedia. (05 Mar 2000) |
| intermediate great muscle | <anatomy, muscle> Origin, upper three-fourths of anterior surface of shaft of femur; insertion, tibial tuberosity by way of common tendon of quadriceps femoris and patellar ligament; action, extends leg; nerve supply, femoral. Synonym: musculus vastus intermedius, crureus, femoral muscle, intermediate great muscle, intermediate vastus muscle. (05 Mar 2000) |
